BBS DIRECT to MAKE LONG-DISTANCE CHARGES OBSOLETE
              with REVOLUTIONARY PRIVATE DATA NETWORK BUILT
              with RACAL-DATACOM EQUIPMENT

              A press conference held at ONE BBSCON, Atlanta, GA
              revealved the following information:

       Concentric Research Corp. announced it has agreed to buy
       network equipment and services valued at $9.5 million from
       RacalDatacom Inc. The equipment will be used to deploy a
       frame relay data communication network to launch the
       revolutionary new BBS Direct service.

       BBS Direct is Concentric Research's new service that will
       revolutionize the way consumers connect to the nation's
       60,000 electronic bulletin board services (BBS).  Customers
       now pay long distance telephone charges to connect to bulletin
       boards.  With BBS Direct, they will pay a flat rate of $30 a
       month for unlimited access via CRC's network.

       "We make long distance usage charges for BBS callers
       obsolete," said Marc Collins-Rector, Concentric Research's
       president and chief executive officer.

       BBS Direct users will dial a local telephone number to
       connect to the new CRC Network, a dedicated data network that
       will use Racal-Datacom equipment and AT&T InterSpan Frame-
       Relay Service.

       "We chose Racal-Datacom because we needed the highest-quality
       networking equipment available," Collins-Rector said.  "The
       engineering integrity of Racal-Datacom equipment is
       unparalleled.  This will guarantee that our fram relay
       network is the best in the country and that it has the
       highest quality equipment in place from the start."

       "Racal-Datacom is proud to be a supplier to this innovative
       new network and what the network will mean to the millions
       of people using electronic bulletin boards," said James K.
       Norman, president of Racal-Datacom.

       Deployment of BBS Direct has started, and the official launch
       service is planned for late September.  Initially, the
       network will offer local dial-up access in the 100 largest
       metropolitan areas, expanding to 350 points of presence in
       the next 18 months.  In addition, "800"-number service will
       be established for customers outside the points of presence.
       Thirty of the nation's largest BBSs are charter members of
       BBS Direct and will be accessible at the time the network is
       in place.  Other BBSs will be added quickly once the network
       is established.

       "Some of the best information available electronically can
       be found on independent bulletin boards," Collins-Rector
       said.  "Until BBS Direct, the only way to access most of
       these services is by using long-distance voice lines and
       paying long-distance rates."

       Users of BBS Direct will have the added benefit of having
       full access to the Internet and to Concentric Research's
       CRIS on-line information and entertainment network.

       The Racal-Datacom Excalibur ASET-1 (analog single-ended T-1)
       will enable computer users over a widespread area to access
       bulletin boards on the service by enabling remote calls to be
       consolidated on high-capacity, cost-effective and
       high-performance T-1/T-3 circuits.  Corporations with large
       computer networks long ago learned the economy of T-1/T-3,
       and BBS Direct will enable bulletin board users to enjoy
       similar savings.

       Also included in the contract are Racal-Datacom INX 5000
       intelligent hubs and CMS 400 and CMS 6000 components of the
       Racal Mangement System.  As a Wellfleet value-added reseller,
       Racal will also provide Wellfleet routers for the CRC Network.
